If all you have is hang on filters for circulation, That would be your problem.
You need to get a power head, Or 2 would be even better.
In my 30 I run a 125Gph and a 175Gph giving a total of 300Gph.
Which most consider a minimum flow at X10 the size of the tank.

OK I will buy a power head next week. So since I got no replies on what I can add to my clean up crew should I assume that there is nothing that likes to eat this type of algae? All I have for clean up now a CBS and a turbo snail. Is there something I should add to help prevent other algae from starting up?

Thanks

I don't know if they will eat it but some Nassarius snails will help by moving the sand bed a bit.
Scarlet hermit's are allways cleaning the sand so some of those may help as well.
Cerith snails may work as well, But im not a big fan of them.
They allways seem to end up on there backs.

Thanks for the help everybody.
